Potential Energy Surfaces and Transition Moments of Cl Atom in Xe Solid Matrix.
STATE UNIV OF NEW YORK AT BUFFALO DEPT OF CHEMISTRY
Pagination or Media Count:
Xe solid containing a Cl atom is considered by the semiempirical diatomics-in-ionic-systems method which takes into account the charge delocalization in an ionic state and the coupling between the neutral and ionic states. The calculation shows that the Cl atom has motional freedom in substitutional trapping sites which leads to the broadening of absorption bands. The vertically accessed ionic states are treated as Xe12Cl- molecules with a nonuniform positive charge distribution. The most stable ionic complex has the Xe2Cl- molecular configuration. Cl atoms at interstitial sites are treated as Xe6Cl molecules with X6Cl- excited states. The results of the calculation are in general agreement with recent experiments.
